Product details
Overview
JANTXV1N4128C-1 from Microsemi is a 500 mW, 60 V Zener diode in DO-35 glass package, qualified to JANTXV level per MIL-PRF-19500/435, with ±2% voltage tolerance, 400 Ω dynamic impedance at 250 mA, and max reverse leakage of 0.01 µA at 45.6 V - used for precision voltage reference and regulation in military-grade power supplies.
For engineers reviewing the JANTXV1N4128C-1 datasheet, JANTXV1N4128C-1 pinout, JANTXV1N4128C-1 application, or JANTXV1N4128C-1 equivalent, this page delivers verified electrical specs, thermal derating behavior, noise density (≤1 µV/√Hz), temperature coefficient (+0.100 %/°C), and mil-spec qualification status - all critical for high-reliability analog design and radiation-tolerant systems.
Technical Context
This device operates as a metallurgically bonded, hermetically sealed Zener regulator optimized for stable voltage reference under wide current (250 mA test point) and temperature (-65°C to +175°C) ranges. Its low noise density (<1 µV/√Hz below 6.8 V) and minimal capacitance support precision analog signal conditioning.
Designed for high-reliability environments, JANTXV1N4128C-1 meets MIL-PRF-19500/435 requirements at JANTXV level, features RoHS-compliant plating (commercial versions only), and exhibits inherent radiation hardness per Microsemi MicroNote 050 - making it suitable for aerospace, defense, and nuclear instrumentation applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4128US-1 | Same 60 V, ±2% spec but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy chassis mounts | Select when automated SMT production and board space constraints outweigh lead-forming flexibility |

FAQ
What is the Zener voltage and tolerance of JANTXV1N4128C-1?
JANTXV1N4128C-1 has a nominal Zener voltage of 60.0 V at 250 mA test current with a ±2% tolerance, confirmed per Microsemi T4-LDS-0245-2 Rev. 1. This tighter tolerance enables higher-accuracy voltage references compared to standard 5% Zeners, and is validated across the full JANTXV qualification temperature range (-65°C to +175°C).
Is JANTXV1N4128C-1 RoHS compliant?
JANTXV1N4128C-1 is not RoHS compliant - RoHS-compliant plating (matte-tin) is available only on commercial-grade versions (e.g., 1N4128C-1e3), not on JANTXV or higher mil-spec variants. The JANTXV1N4128C-1 uses traditional tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability under military environmental stresses.
What is the maximum power dissipation and thermal derating behavior of JANTXV1N4128C-1?
JANTXV1N4128C-1 has a rated average power dissipation of 500 mW at 25°C, linearly derated to zero at 175°C. Derating begins at 50°C for lead temperature (TL) and at 25°C for ambient (TA) on typical FR4 boards. Thermal resistance is 300°C/W junction-to-ambient and 250°C/W junction-to-lead (3/8″ lead length), per Microsemi T4-LDS-0245-2.
Does JANTXV1N4128C-1 have radiation hardness certification?
Yes - JANTXV1N4128C-1 exhibits inherent radiation hardness as documented in Microsemi MicroNote 050. It is not individually tested per MIL-STD-883, but its metallurgically bonded, hermetically sealed DO-35 construction provides proven resilience to total ionizing dose (TID), making it suitable for low-to-moderate radiation environments without additional shielding or derating.
What is the noise performance of JANTXV1N4128C-1, and how is it measured?
JANTXV1N4128C-1 has a maximum noise density of ≤1 µV/√Hz, measured using a 1 kHz–3 kHz bandpass filter at 25°C ambient and 250 mA Zener test current (IZT). This low noise supports precision analog applications such as ADC reference buffers and low-drift sensor excitation circuits, as specified in Microsemi T4-LDS-0245-2 Figure 1 and notes.
